The field of research of this paper combines Human Computer Interface, gesture recognition and fingertips tracking. Most gesture recognition algorithms processing color images are unable to locate folded fingers hidden inside hand contour. With use of hand landmarks detection and localization algorithm, processing directional images, the fingertips are tracked whether they are risen or folded inside the hand contour. The capabilities of the method, repeatibility and accuracy, are tested with use of 3 gestures that are recorded on the USB camera. Fingertips are tracked in gestures presenting a linear movement of an open hand, finger folding into fist and clenched fist movement. In conclusion, a discussion of accuracy in application to HCI is presented.

The use of welfare support by EU migrants has dominated media coverage and political debates about EU migration in the UK for several years, regularly featuring claims about the negative effects of the presence of EU migrants on the UK social security system. Such claims became particularly prominent in 2013–2015, during the UK government’s campaign to limit EU migrants’ access to UK welfare benefits and in debates prior to the Brexit referendum. This article sheds light on how Polish migrants position themselves concern-ing the claiming of welfare benefits in the UK and how this affects their welfare strategies. The article is based on 14 qualitative interviews conducted in Liverpool 18 months after the Brexit referendum. Using stigma and benefits stigma as an overall theoretical framework, we find that the informants, in their posi-tioning narratives, 1) put forward similar stigmatising expressions and stereotypes regarding the use of wel-fare as those featured by politicians and the media, which points to perceived abuse; 2) make a distinction between in-work and out-of-work benefits, the first being more acceptable than the second; 3) prefer living on savings or accepting ‘any job’ over making use of out-of-work benefits, which points to an underuse and/or to possible processes of marginalisation; and 4), a tendency among those who have experience with claiming out-of-work benefits to question the discourses of welfare abuse. Finally, ‘working’ and ‘contrib-uting’ to the system as opposed to relying on welfare support is perceived as a precondition to staying in the UK after Brexit – welfare and work are seen to signal very high stakes indeed.

The Author discussed in his article the problem of ethic foundations of promoters of psychohistory. He argues that psychotherapeutic inclinations of scholars resulted in the alienation of this approach within historical sciences, what — in the end — did not prevent psychohistorians from becoming active outside the closed circle of the discipline.

The model of the equations of generalized thermoelasticity in a semi-conducting medium with two-temperature is established. The entire elastic medium is rotated with a uniform angular velocity. The formulation is applied under Lord-Schulman theory with one relaxation time. The normal mode analysis is used to obtain the expressions for the considered variables. Also some particular cases are discussed in the context of the problem. Numerical results for the considered variables are obtained and illustrated graphically. Comparisons are also made with the results predicted in the absence and presence of rotation as well as two-temperature parameter.
